Patent GB-2479182-A (GB)
Title: RF Power Amplifier
Inventor: CLIFTON JOHN CHRISTOPHER
IPC: H03F1/02
Filed: 2010-03-31
Abstract: A power amplifier comprises a series stack of power amplifier devices 2, AC-coupled (6) to the amplifier input 3 for receiving an RF input signal. The amplifier devices 2 are connected in series, for RF signals, to the amplifier output 5. An intermediate coupling capacitor 8 is connected between each adjacent pair of power amplifier devices in the series stack. The coupling capacitors 8 provide DC isolation between the power amplifier devices 2. Each power amplifier device has its own DC supply terminals 7 and 9. The intermediate coupling capacitors 8 thus allow the transistors to be biased in parallel, even though they are arranged in a series stack to increase the voltage of the RF signal. This reduces the required DC supply voltage, and avoids the need for a DC-DC converter. The circuit also allows shorting of individual power amplifier devices in response to variation in the DC supply voltage. The circuit provides improved bandwidth for multi-band applications. Keywords: JPHEMT, PHEMT, WCDMA / LTE, 3G, 4G, GSM / EDGE, GPP, GSM.

Title: Generating partitions of a communications network
Inventor: WALSHAW CHRIS H
IPC: H04L12/24
Filed: 2010-05-17
Abstract: A population of partitions (So,S1.... ) of a communication network (312) having different optimisation objectives is generated in a cascading manner. A preferred solution or partition can be selected from the population and the communications network (312) can be configured accordingly. Partitions of the communications network are generated by providing a graphical representation (102) of the communications network, generating a first, balanced partition (So; 118) of the communications network (312) in which a network balancing constraint is imposed, and generating a second, unbalanced partition (S1, S2,) of communications network (312) in which a network balancing constraint is relaxed.

Title: Selecting shapes in a graphical display for removal from memory
Inventor: CAMPNEY BRUCE HUBERT
IPC: G06T1/60
Filed: 2010-10-12
Abstract: A selector shape may serve as the background to a configurable composite shape and may include one or more expressions that are evaluated to select between several composite shape definitions via links to the definition. Each selector shape includes an animation expression and a lookup table converter to select an identifier of the composite definition to be loaded and displayed. When the value of the animation expression changes, the value may be matched to the name of a new composite definition using the lookup table, and the new definition may be displayed. The previously-used composite definition may then be marked for removal by a caching system, and removed. These selector shapes also enable the same graphic element to be used in displays designed for different types of display devices, such as display devices having large display screens, standard computer screens and very small display screens.
